Duplicate and triplicate activities

Former Member over 8 years ago

I have an Edge 1000 that I use to record my cycling - I was looking over the Garmin Connect summary for 2016, and noticed several months (July, August, September) with what seemed unusually high distance covered. When I have a look at the activities for these months, I can see that quite a number of rides have not been detected as duplicates and are in the list of activities two, three, and occasionally four times over - same date, start time, and distance. I assume this is a bug somewhere in the sync process. I sync by connecting the Edge 1000 to my PC via USB and then use Garmin Express (Windows version).

More recent months are free of the duplicated activities...

Do you use any other apps, such as MyFitnessPal? There have been reports in the past with multiple apps syncing the same activity to Garmin Connect

The only other app I ever use with Connect is the Connect Android app, and I haven't used that to sync since I was in Europe in May and June.

Duplicate sync happened again on yesterday's ride. Only happens when I sync my Edge 1000, not when my wife syncs her Edge Explore 1000. Screenshot attached.

Duplicate activities are being uploaded after pairing a new HRM-Tri Heart Rate Monitor with the fenix 6 (software version 9.00). Despite the identical results that would be expected for a duplicate, the Avg HR, Training Effect, and other quantities are different. Calories can have greater than a 50% difference for the same activity, as shown below (178 C vs 117 C for the Walking activity), despite the graphs of heart rate over time being nearly identical for the duplicates. It appears that others have had similar issues, as at the linked example below for the Forerunner.

Why are the Calories so different between duplicate activities? More importantly, can further duplicates be avoided while the using the more accurate version for Training Effect, Calories, etc?

I have the same problem, randomly activities especially running and cycling are duplicate which affects everything from fitness level to training status, I have to keep deleting the duplicates. There is a small difference in terms of heart rate and am using HRM Tri. I am not using any other App or device to record my activities. I sync with Strava. Would it be possible that Strava writes back in Garmin because, the second duplicate comes couple of hours later..
